Module Setup

Setup

Anywhere motion-motor-expression-step.jpg
  • Assemble modules and sensors together:
    • Connect two motors to Motor module;
    • Stick the red core, yellow motion module and green motor module to the yellow battery base;
    • Plug one end of USB cable into the battery base and connect the other end to computer.

Programming

Required Program Blocks

Start to Program

Motor begin Motion DMP solution Variable X is for storing the pitch motion degree Constrain X to -20~20 Map X from -20~20 to -255~255 Send X to the serial monitor The speed of the two motor is X.

Test the result
Before power on, confirm the motion module is level, and the x axis of motion sensor leans downward, and the two eyes turn left (anticlockwise); the x axis of the motion sensor leans upward, and the two eyes turn right (clockwise).

Q: Now the two eyes turn to the same direction. How to make them turn to different directions?
A: -255~0 represent rotating back, and 255~0 represent rotating forth, just change x into –x can make it rotate reversely.

Use variable Y to storing the roll motion degree. Constrain Y to -20~20. Map Y from -20~20 to -255~255. The speed of motor 1A,1B is X-Y. The speed of motor 2A,2B is X+Y.
